A vitamin A deficiency test measures the amount of vitamin A in your blood. It is ordered when a person has symptoms or risk factors that suggest low vitamin A, such as poor night vision, dry eyes, or difficulty seeing in dim light. It can also be used to monitor people with conditions that affect how the body absorbs fat and fat-soluble vitamins.
What it measures
- Retinol — The main form of vitamin A circulating in the blood; this is the most common marker measured.
- Retinyl esters — A storage form of vitamin A; high levels may suggest too much vitamin A.
- Beta-carotene — A plant-based precursor that the body converts into vitamin A; sometimes measured to assess intake.
- Retinol-binding protein — A protein that carries vitamin A in the blood; low levels can occur with poor nutrition or liver problems.
Who it is for
A clinician may order this test for people with symptoms of vitamin A deficiency, such as night blindness or dry eyes, or for those with conditions that cause poor absorption of nutrients, including certain digestive disorders or a history of weight-loss surgery.

Results and what they mean
